“The Bubble Universe” –A New Model of the Cosmos

As Peter Woit, a theoretical mathematician at Columbia University says, string theory “is not even wrong” because it is not falsifiable –a basic tenet of all science theory. Now, Uppsala University researchers have devised yet another “new model” for the universe based on string theory – one with the added bonus they propose may solve the enigma of dark energy.

Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.

We have known for the past 20 years that the universe is expanding at an ever accelerating rate. The explanation is the “dark energy” that permeates it throughout, pushing it to expand. Understanding the nature of this dark energy is one of the paramount enigmas of fundamental physics.
